I don't want to be too harsh, but this is a pattern with Parallels products. You offer new versions for sale frequently and advertise how awesome you are to include features provided by open source software, and then rarely if ever actually update the available versions of the software for which you hype the features. This is true with Parallels Panel/Plesk/Virtuozzo where it becomes a huge security risk unless one goes "off script" and starts manually maintaining the packages on the virtual machine. And then, what's the point of having Parallels? You consistently have software packages that are three or four or five years out of date.
You take our money every nine or ten months; we deserve better than outdated packages that you don't have to pay for anyway.
(Yes, I know that it takes effort to keep things up to date: I have to do that effort myself and I have to put in a lot more work than I normally would because I have to tapdance around your systems. Hence my proposed slogan: "Parallels Panel: if you think Linux system administration is just too easy." And yes, I know, this is about Parallels Desktop. I'm just pointing out that providing ChromeOS from 2011 is part of your corporate pathology.)
